138100-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138100-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,1,0 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138100-18:
(8*1)+(7*3)+(6*8)+(5*1)+(4*0)+(3*0)+(2*1)+(1*8)=92
92 % 10 = 2
So 138100-18-2 is a valid CAS Registry Number.

In a model study aimed at the total synthesis of clerodin 1, the tricyclic furo-furan moiety 2 was prepared. This approach was based on a stereoselective Claisen rearrangement between a cyclohexenol and a cyclic orthoester.
